The counter-point, from the publisher of "Skeptic" magazine, takes an expected opposite view, one often also a matter of selective evidence considered. Presented partially for balance, also as an example of the other side of the coin, and to underscore the sometimes confusion of evidence versus proof. It's all in the details and if/what details one wants to examine and consider. Hancock can get off on some 'deep woods' tangents, but in many ways his and similar perspectives tend to be a bit more open minded than the strictly conventional mindsets.

Here's another article on what is a regular "threat" window, the Taurid Meteor Streams (TMS), which are connected with Comet Encke;Earth Faces an Increased Risk of Being Hit by an Asteroid, Astronomers Warn

Large asteroids may be lurking undiscovered within a meteoroid stream whose particles are hitting Earth, and scientists are urging a concentrated search for them.
...
Most of these particles are quite tiny and pose no threat whatsoever, but the Czech astronomers have tracked a new branch of the stream from which particles are intersecting with the planet. The branch includes two asteroids with diameters of between 200 and 300 meters (roughly 650-1000 feet). These asteroids are not themselves on a collision course with Earth, but their identification suggests that there may be other asteroids of this size or larger lurking undiscovered within this stream.

The threat/danger of the TMS was raised about twenty years ago by Richard C. Hoagland in the following article/link. While some of this relates to "conspiracy theory' material of past and questionable concern, the middle part of the article provides interesting text and illustrations on the TMS and possible past historical impact events, such as following excerpt;

Leading astronomers of the last half-century like Fred Whipple, Victor Clube, and William Napier have done extraordinary work pointing out that the Taurid stream seems to be the strung out remnants of a mega comet, an object at least several hundred kilometers in diameter which broke up only 20,000 years ago. The stream is thought to be lead by comet Encke, the shortest (3.3 years -- 1/10th 33 ..!) periodic comet known. The stream of debris orbits in an "Earth Crossing" elliptical pattern, a "tube" essentially 30 million kilometers wide. We cross this stream like clockwork twice a year, from June 24th through July 6th, and from November 3rd through November 15th. As you can see, we annually spend some 24 days in the grips of the Taurid's trail. Since the Earth's crossing time for most other meteor streams is just a few hours, volume for volume and mass for mass, the source object of the Taurid stream may be about a million times larger than a "typical" one.

In pointing out several periods of multiple impact events in the past (one coinciding with the construction of Stonehenge) due to a disturbance or fragmentation in the stream, Clube and Napier discern that there must be several massive "hidden" comets in the stream, dormant comets invisible to our telescopes buried in the dust and debris.

Whipple, for one, concurred. He pointed out that Encke, some 5 kilometers across, most probably had several dormant and even larger companions. In addition there have so far been two other comets identified in the stream and 13 Earth crossing asteroids.

The 300,000-year-old bones and stone tools were discovered in a surprising place—and could revise the history of our species.
...
Hundreds of thousands of years ago, around 62 miles west of what would eventually become Marrakesh, a group of people lived in a cave overlooking a lush Moroccan landscape. They rested there, building fires to keep themselves warm. They hunted there, sharpening stone tools to bring down animals. And they died there, leaving their bones behind in the dirt. At the time, there would have been nothing particularly notable about these cave-dwellers. They were yet more Homo sapiens, members of a nascent ape species that had spread across Africa. But in their death, they have become singularly important.

That cave is now called Jebel Irhoud, and bones of its former occupants have been recently unearthed by an international team of scientists. They mark the earliest fossilized remains of Homo sapiens ever found. Until now, that honor belonged to two Ethiopian fossils that are 160,000 and 195,000 years old respectively. But the Jebel Irhoud bones, and the stone tools that were uncovered with them, are far older—around 315,000 years old, with a possible range of 280,000 to 350,000 years.

These people had very similar faces to today’s humans, albeit with slightly more prominent brows. But the backs of their heads were very different. Our skulls are rounded globes, but theirs were lower on the top and longer at the back. If you saw them face on, they could pass for a modern human. But they turned around, you’d be looking at a skull that’s closer to extinct hominids like Homo erectus. “Today, you wouldn’t be able to find anyone with a braincase that shape,” says Gunz.

The Human Brain Can Create Structures in Up to 11 Dimensions
"We found a world that we had never imagined."

EXCERPT:

Neuroscientists have used a classic branch of maths in a totally new way to peer into the structure of our brains. What they've discovered is that the brain is full of multi-dimensional geometrical structures operating in as many as 11 dimensions.

We're used to thinking of the world from a 3-D perspective, so this may sound a bit tricky, but the results of this new study could be the next major step in understanding the fabric of the human brain - the most complex structure we know of.

This latest brain model was produced by a team of researchers from the Blue Brain Project, a Swiss research initiative devoted to building a supercomputer-powered reconstruction of the human brain.

The team used algebraic topology, a branch of mathematics used to describe the properties of objects and spaces regardless of how they change shape. They found that groups of neurons connect into 'cliques', and that the number of neurons in a clique would lead to its size as a high-dimensional geometric object.

"We found a world that we had never imagined," says lead researcher, neuroscientist Henry Markram from the EPFL institute in Switzerland.

"There are tens of millions of these objects even in a small speck of the brain, up through seven dimensions. In some networks, we even found structures with up to 11 dimensions."
